摘要： In a multi-user communication system, a pre-coder in a transmitter comprises a Discrete Fourier Transform (DFT) spreader provides data symbols spread with Fourier coefficients to generate DFT-spread data symbols. An OFDM modulator, such as an inverse-DFT, modulates the DFT-spread data symbols onto OFDM subcarriers to produce a pre-coded OFDM transmission signal. The Fourier coefficients reduce the transmission signal's peak to average power.

摘要： In a wireless communication system, a receiver comprises an Orthogonal Frequency Division Multiplexing (OFDM) demodulator configured to demodulate a spread-OFDM signal transmitted from a user equipment (UE) to produce demodulated data symbols corresponding to OFDM subcarriers assigned to the UE. A discrete Fourier transform (DFT)-based despreader is configured to despread the demodulated data symbols to produce estimates of original data symbols, wherein the despreader employs a DFT despreading code corresponding to a DFT spreading code employed by the UE to shape the spread-OFDM signal into a plurality of uniformly spaced pulse waveforms modulated with the original data symbols. A frequency-domain equalizer may be provided to equalize and/or spatial deumultiplex the demodulated data symbols before despreading.

A destination node may select a set of receiving nodes to cooperatively receive the transmissions.

摘要： Instead of just consuming network resources, client devices create network resources via cooperative subspace processing to increase data bandwidth and expand radio coverage so the network grows dynamically with demand. Server-side cooperative-MIMO provides joint processing for geographically distributed base stations with overlapping coverage areas. A combination of centralized coordination and distributed computing pools and virtualizes base station processing, which reduces complexity, size, and power requirements of base stations to facilitate rapid and inexpensive network deployments. Cooperative subspace coding reduces overhead and transport-layer inefficiencies, and enables each channel to simultaneously employ multiple network paths, even over non-homogeneous networks. Cooperative subspace processing enables a client in a first network to reuse its allocated channels for communicating in another network without interfering with the first network.

摘要： A cooperative multi-user multiple input, multiple output (MIMO) system coordinates spatially distributed transceiver stations for communicating with wireless client devices. The system comprises a network interface communicatively coupled to the transceiver stations via a backhaul network, which may comprise a wireless local area network. A MIMO processor pre-codes NR original data streams to generate NT subspace-coded data streams, wherein each subspace-coded data stream comprises a linear combination of at least some of the original data streams. NT may denote a number of transmitting antennas, and NR may denote a number of receiving antennas. A network controller conveys the subspace-coded data streams to the transceiver stations via the backhaul network and coordinates the simultaneous transmission of the subspace-coded data streams over wireless links to the wireless client devices. The pre-coding causes the transmissions to coherently combine at a first wireless client device to produce at least a first data stream while suppressing inter-user interference from at least a second data stream intended for at least a second wireless client device. The client devices and/or the transceiver stations may be selected based on channel state information and/or measured channel quality.

摘要： An OFDM transmitter spreads original data symbols with a complex-valued spreading matrix derived from a discrete Fourier transform. Spread data symbols are mapped to OFDM subcarriers. Spreading and mapping are configured to produce a transmitted spread-OFDM signal with a low peak-to-average power ratio (PAPR) and orthogonal code spaces. In MIMO systems, the complex-valued spreading matrix can comprise a MIMO precoding matrix, and the code spaces can comprise MIMO subspaces. In Cooperative-MIMO, a combination of low code-space cross correlation and low PAPR can be achieved.

摘要： Disclosed techniques for improving computational efficiency can be applied to synthesis and analysis in digital signal processing. A base discrete-time Orthogonal Frequency Division Multiplexing (OFDM) signal is generated by performing at least one linear transform, including an inverse discrete Fourier transform (IDFT), on a first matrix of data symbols. A sparse data matrix is provided as an update to the first matrix of data symbols. The at least one linear transform is performed on the sparse data matrix to generate an update discrete-time OFDM signal. The update discrete-time OFDM signal and the base discrete-time OFDM signal are summed to produce an updated discrete-time OFDM signal.

摘要： A computer-implementable method employs radio signal metadata to train a cognitive learning and inference system to produce an inferred function, wherein the metadata comprises a syntactic structure of at least one radio communication protocol. The inferred function is used to map metadata of a detected radio signal to a cognitive profile of a transmitter of the detected radio signal. The mapping effects intelligent discrimination of the transmitter from at least one other transmitter through corroborative or negating evidentiary observation of properties associated with the metadata of the detected radio signal. A response to the transmitter is based upon the mapping.
